1：The Dreaming

The Drenming is the belief system from ancient times that has bound indigenous groups together .The central principle of the dreaming is that the people who live on the continent have special responsibilities to the land .The people don’t own the land ,instead the land own the people .The stories of the dreaming provide principles of how people should live and interact with each other .They also provide knowledge of the land so that the indigenous people can survive in the life—threatening environment .

In 1782, the french who settled in pennsy first asked the question " what is an American" in his book Letters from An American Farmer.

The New world of america was peopled as a result of two long-continuing immigration movements, the first one from Asia and the second from Europe and Africa.

American indians had developed three brilliant civilizations before the Europeans arrived. These three civilizations were the Aztecs, the Incas and the Mayas. Columbus discovered the new world in the year of 1492

1. 对于四方配位场(7.1.1), 当点电荷与中心的距离不等, 但符合|±x|<|±y|时, 则中心原子的p轨道和d轨道的能级图7.3(a)及(b)将发生什么变化? 请根据你的直觉和简单分析做出最合理的判断, 画出能级图.

解:当点电荷距中心距离不等时, 将导致在正四方配位场下的二维不可约表示进一步分裂为

两个一维不可约表示,即 px, py, 和 dxz, dyz轨道进一步分裂.

若|±x|<|±y|, 则px将比py感受道更强的来至点电荷的排斥作用, 从而导致px能量高于py.

dxz, dyz轨道的能量也将发生分裂, 但是由于点电荷不在轨道的最大值方向, 感受的排斥相对于px, py要小. 故能级的分裂值较小, dxz较高, dyz较低. 能级图如下:

pxdx-ydxypydxzdyz222pzEEdz自由原子px, py, pzd自由原子

2. 反式四配位配合物 t?MA2B2, 如[PtCl2Br2]2?及Pt(NH3)2Br2的几何对称性为D2h,请以[PtCl2Br2]2?为对象, 给出其中的八个对称操作, 并将中心原子的原子轨道:{s, px,py,pz,dz, dx?y,dxy,dxz,dyz}按D2h不可约表示分类;若按D2h的子群D2分类, 结果又如何?(提示:参考特征
